open the firefight folder on your computer and do dat and then infantry foulders and there a bunch of notepad files copy one and then double clikc on it. There should be tings like the name of the sqaud and Man=REGULAR, WEAPON_SMG, 120, 4, no
that is an example man REGULAR can be changed to RAW or ELITE depending on how good you want him to be SMG or Mortar or Rifle or whatever and 120 is hom much of his gun amo and the 4 is how many grenades no means is he assistant to the gunner above him i think thats for mortars and hmg's and i think there is a country thing. to if im not very understandable post a question or something.
